nourishing Allergy

The nourishing allergy is one of the most common causes that it causes prurito in dogs and the problem is commonly a food that the dog has eaten from long ago. The cause is the protein in the food - meat, fish, poultries the protein molecules are great and complex, they are similar somehow to ?antigens? that are on virus and bacteria. In some dogs, after the repeated or prolonged exhibition to particular an nourishing protein, the immune system begins to react. The result is an nourishing allergy.

In the American Hospital of the Left Animal a project with 51 dogs suspected that was made in 1999 they suffered nourishing allergies. The main sign in all the dogs was prurito. Most of them it had ears inflamed with picazón and they are complicaban with infections of the ear. In some cases, the ears were the only affected region. The inguinal zone, previous armpits, members were the second commonest affected zone. Most of the dogs they were of 1 to 3 years of age, but some were younger and some older. The most common races were Farmers, Cocker Spaniels, and Shepherds German.

Each dog put itself to diet that contained a diet that never had ingested previously. In most of the cases this one it was lamb and rice. The allergy symptoms went completely in some of the dogs after 1-3 weeks on the special diet but the majority took a month or two to them to be observed an improvement. After the dogs were all ?cured,? it is administered to him, again, the previous diets. Some dogs began to have prurito to the few hours, and the others are rascaban again in one week.

It can be difficult to find a novel protein source for his dog in supermarkets. But there are products of special prescription available in Veterinary Clinics, and these diets are with duck, deer, turtle, being easiest to obtain and with good results - the lamb, the last protein that is being used is the obtained one from kangaroo meat; but it is necessary to stress that the results of a diminution and disappearance of the prurito will be within the 2 or 3 months of to have begun with the new diet.

The mechanism of action of as the protein it produces the prurito is due to the high molecular weight of the same ones and the immune system recognizes like an antigen triggering the allergic reaction, the capacity of a protein of the diet to cause hypersensitivity seems to depend on the size and the structure of the protein, when its molecular weight oscillates between 18000 and 36000 daltons.

The special foods are elaborated of a way where the proteins ?are fragmented? obtaining particles with a molecular weight smaller to 18000 daltons. The immune system would not have ?to recognize? these small protein fragments and they would not have to react them in front of. During the digestion, the protein is transformed into still smaller fragments, anyway, this would not have to affect the nutritious quality of the protein. Theoretically, if its dog have an nourishing allergy, the prurito and the affections of the auricular pavilion would have to disappear less after three months or.
